	The New York Public Library atFifth Avenue and Forty-Second Street...
:00:24
	was the locationof this opening scene.
:00:27
	Originally conceivedas two separate establishing shots...
:00:30
	Director Ivan Reitmanand Cinematographer Lazlo Kovacs...
:00:32
	chose instead this sweepingcrane shot.
:00:37
	This interior is the Main Reading Roomof the New York Library.
:00:40
	To film herewas a logistics challenge.
:00:42
	The huge room had to be lit,the action staged and photographed...
:00:45
	and then everything cleared away...
:00:48
	all within the hoursbetween the crew's 5:00 AM call...
:00:51
	and the Library's 10:00 AM opening.
:00:57
	We're not in New York anymore.
:01:00
	While the New York Library exteriorand vast reading room...
:01:03
	created a perfect Gothic atmosphere,the book stacks flunked their audition.
:01:06
	For "aesthetic and economic reasons,"the producers shot these scenes...
:01:09
	at the main branchof the public library in Los Angeles.
:01:11
	The final shooting scriptcalled for more than a dozen books...
:01:14
	to suddenly fly off the shelfand land at the feet of the librarian.
:01:17
	But at the last minute,Dan Aykroyd suggested...
:01:20
	this more subtle and eerie approach...the first of 200 optical effects...
:01:23
	by visual effects creatorRichard Edlund and his team.
:01:37
	This next bit of ghostly mischief...
:01:40
	falls in the category of a physicaleffect rather than an optical effect.
